After reading The Book With No Pictures by @bjnovak , I asked my 4 year old preschoolers: What does the word Blork mean to you?
  1. "It means you're holding a heavy board."
  2. "It means bonk."
  3. "If you have a piece of wood and you throw it down the hole and you can't find it."
  4. "It's a bird!"
  5. "That you're silly."
  6. "When you bump into something and it tickles."
  7. "The sound you make when your burp."
  8. "It means you bump into a cat and Blork your head."
